Datasets. We conducted experiments on four long-tailed classification datasets:
CIFAR100-LT [1]}, Places365-LT [2]}, ImageNet-LT [2]}, and iNaturalist 2018 [4]}.
The imbalance ratio (IB) is defined as \(N_{\max }/N_{\min }\) , where \(N_{\max }\)  (\(N_{\min }\) ) denotes the largest (smallest) number of class samples. A larger IB denotes a more imbalanced split. Details of the datasets are in Table REF .
See Appendix for further details.
